When creating an SQL View without SRS, the BasicResourceConfig page still tries to guess the Native SRS, resulting in strange behavior and throwing error
```Error getting actual Native SRS code for resource ADRESSER: java.lang.NullPointerException```
Steps to Re-produce
-Run Geoserver with Oracle Datastore enabled
-Create Oracle table with SDO Geometry, Metadata entry and index following example Oracle SDO Geometry Example
-Create an SQL View using SQL (select * from COLA_MARKETS)
-Don't set the SRID and submit the view
-Verify log error Error getting actual Native SRS code for resource ADRESSER: java.lang.NullPointerException`
